3.16 Secondary Water Chemistry DhhM Applicability A D

'T R Objective b U d d)

To maintain steam generator feedwater chemistry within values without potential for degradation of steam generator tube walls.

Specification 3.16.1 The reactor shall not be taken or maintained above hot shutdown con-ditions unless the total cation conductivity limits of Table 3.16-1 are met except as provided below.

3.16.2 If the total cation conductivity of the steam generator feedwater is found to exceed the Steady State Limit of Table 3.16-1 but is within the Transient Limit of Table 3.16-1, it shall be verified at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> that the pH and maximum total solids in the steam generator feedwater are within the limits of Table 3.16-1 and the conductivity shall be restored to within its Steady State Limit within 7 days; or the reactor shall be placed in the hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

3.16.3 If, during the conditions described in 3.16.1 requiring surveillance of steam generator feedwater pH and/or maximum total dissolved solids, said pH and/or maximum total dissolved solids are found to exceed the limits of Table 3.16-1 they shall be restored within the limits of ,

Tabic 3.16-1 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or the reactor shall be placed in the hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

3.16.4 If the total cation conductivity of the steam generator feedwater

.

is found to exceed the Transient Limit of Table 3.16-1 it shall be restored to within the Transient Limit of Table 3.16-1 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or the reactor shall be placed in the hot shutdown con-dition within 12 ho'urs. -

• 3.16.5 No report per specification 6.12.3.2 will be required unless the above requirements necessitate placing the reactor in the hot shutdown condition.

.

Bases Msintaining the steam generator feedwater within the limits of this specifi-cation will control the introduction of potentially corrosive impurities into the steam generators and minimize tube degradation.

4.18 Secondary Water Chemistry Surveillance

]

I g .icability Ap,slies to-the surveillance of steam generator feedwater chemistry.

pajective To verify that ' secondary water chemistry is within the limits of specifi-cation 3.16.

Specification At ,least 5 times per week determine that steam generator feedwater chemistry is within the total cation conductivity limits of specification 3.16, Table 3.16-1.

Bases This monitoring provides reiasonable assurance that the potential for undue steam generator tube degrajation has been minimized.
